Furthermore, a recognition of the direct aiming periphery isrendered more difficult.

These drawbacks are avoided by optical aimingdevices. The latter consistmostly of telescopic sights, which are additionally mounted on therifle. Since mostly one deals thereby with sensitive optical and thusalso more expensive instruments, which require, due to their sensitivityagainst blows, a careful treatment, in particular of the setting deviceof the aiming member disposed in the optic, these aiming devices are notsuitable for the general army use, rather only in exceptional cases, forinstance, for sharp shooters.

It is one object of the present invention, to provide an optical aimingdevice for rifles, for the general army use, which, at first, is simplein its structure, and therefore, comparatively economical in itsmanufacture and furthermore, can be secured to the rifle in a simplemanner, protected against blows and shocks.

it is another object of the present invention, to provide an opticalaiming device for rifles, which comprises a telescopic sight equippedwith an immovable aiming member, which telescopic sight is mounted as anindependent part swingably to all sides, as well as securable inside ofa tubular carryinggrip, which is substantially cylindrical, and providedon the weapon.

Aiming devices in connection with the carrying-grip provided on therifle are known. In this arrangement, the carrying-grip has at its upperside a longitudinal trough for receiving a backsight or a diopter, or ithas a telescopic sight secured additionally on the upper side of thehand grip and is thereby exposed to the danger of damages.

It is still another object of the present invention, to provide anoptical aiming device for rifles, which includes an advantageous, yetsimple and simultaneously safe mounting of the aiming device, so thatthe telescopic sight is mounted at one end by means ofa crownedcentering ring in thecarryinggrip and is settable as to its height andtowards the side at its other end by means of known setting meansprovided on the tubular carrying-grip.

In accordance with a further development of the present invention, thetelescopic sight is retained in the carrying-grip by engagement of thecrowned centering ring against a conical shoulder, and by a setting ringscrewable axially into the carrying tube and effecting by means of anelastic intermediate ring on the end side of the telescopic sight. Inthis manner, a holding in axial direction, which holding on the one handis reliable and on the other hand elastic, is obtained, so that therecoil forces of the weapon cannot render a damaging efi'ect.

The simple mounting of the aiming device is made possible in anadvantageous development of the present invention additionally such,that the heightand side-setting device comprises a setscrew, eachdisposed in the wall of the carrying-grip and effecting the housing ofthe telescopic sight, and that springs, inparticular blade springs, arecoordinated to the setscrews and are disposed substantiallydiametrically opposite the set screws and which support themselvesbetween the inner wall of the tube and the housing of the telescopicsight.

As an aiming device, a simple nonadjustable and light optical systemwith a rigid aiming member, and which optical system is only slightlyenlarging. In this manner, the riflernan has a comparatively largeviewing field and can well observe the target as well as its directsurroundings.

derstood in connection with the accompanying drawings, in which:

, FIG. 1 is an axial section of an aiming device disposed within thecarrying-grip of a rifle and designed in accordance with the presentinvention; and

FIG. 2 is a cross section along the lines ll-ll.

Referring now to the drawing, the telescopic sight 1 forming an opticalaiming device is disclosed, and the aiming device comprises an immovableoptical system, and which optical system is not at all or only weaklyenlarging, the optical system having an ocular lens 2, an objective lens3, a reversing lens 4 disposed therebetween, as well as a rigidlyarranged aiming member 5 between the lenses 3 and 4. All parts arerigidly and nonadjustably arranged in the housing of the telescopicsight.

The telescopic sight l forming an independent part is disposed in atubular carrying-grip '7, open at both ends, which carrying-grip 7 issecured by means of two supports 8, as well as by clamping screws 9, ona weapon housing 11, equipped with a dovetail guide 10. It is thuspossible, to remove the carrying-grip 7 with the telescopic sight 1 fromthe rifle and to mount instead a conventional telescopic sight for sharpshooters.

The telescopic sight 1 has at its rear end a centering ring 12, formedcrowned outwardly which comes into engagement during axial insertioninto the tubular carrying-grip with a conical shoulder 13, providedinside of the carrying-grip. By a setting ring 14, axially screwed intothe rearward end of the carrying-grip and by a rubber elasticintermediate ring 15, the telescopic sight is retained in axialdirection. In view of the rubber elastic ring 15, however, an all-sidedswinging of the telescopic sight about the point A is assured. Forsecuring of the vertical position of the aiming member 5, a guide pin 17is inserted radially into the wall of the carrying-grip, which enters agroove 18, disposed in the centering ring 12 in correspondence with theposition of the aim member 5.

Within the range of the viewing end of the telescopic sight,

settingand adjusting-screws are provided on the carrying-grip andeffective upon the wall of the telescopic sight. The heightadjustingdevice comprises a setscrew l9 equipped at its periphery with a linemarker for different aiming distances,

' which setscrew l9 iseffective by means ofa pin 20 on the wall Withthese and other objects in view, which will become ap parent in thefollowing detailed description, the present invention, which isdisclosed by example only, will be clearly unof the telescopic sight,the latter being pressed against the pin 20 by a diametricallyoppositely disposed blade spring 21, which is secured to thecarrying-grip. For a side adjustment, an adjustment screw 22 is providedin the carrying-grip, as well as an oppositely disposed blade spring 23.

in order to maintain the diameter of the carryinggrip at a small scaleand to obtain nevertheless a possibly largest height adjustment range ofthe telescopic sight, for example, up to L000 m., the carrying-grip isslightly inclined relative to the axis of the bore in aiming direction(angle BAC While I have disclosed several embodiments of the presentinvention, it is to be understood that these embodiments are given byexample only and not in a limiting sense.
